Description

Technical Field

[0001] This utility model relates to a foldable device for easy transportation to prevent welding gas cylinders from tipping over, and belongs to the technical field of gas welding equipment. Background Technology

[0002] Gas cylinders are essential equipment in current welding or gas cutting processes. During on-site gas welding or shielded welding operations, gas cylinders are required to store gas to meet on-site needs. Due to the high internal pressure of gas cylinders, impacts or tipping can easily cause components at the cylinder opening to be ejected by the gas pressure, damaging surrounding facilities or personnel. Therefore, anti-tipping devices are needed to stabilize the gas cylinders. Currently, anti-tipping devices are typically constructed by welding a bracket, with the gas cylinder placed inside the bracket. However, in some outdoor operations, it is necessary to transport the gas cylinder and anti-tipping device to the work site. During transportation, the anti-tipping device is relatively large, occupying significant space in transport equipment, making it inconvenient to transport and requiring improvement. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a foldable anti-tipping device for welded gas cylinders that can be transported. This anti-tipping device can be folded, occupies little space, and is convenient for transportation. When opened, it can support the gas cylinder normally and avoid safety accidents.

[0004] The technical solution to the above technical problem is:

[0005] A foldable, transportable anti-tipping device for welded gas cylinders includes a base frame, support rods, a rotating shaft, gas cylinder fixing rings, connecting plates, connecting bolts, and connecting nuts. The base frame is a rectangular frame placed on the ground. A base plate for placing the gas cylinder is located in the middle of the rectangular frame. Two support rods are located at each end of the two side rods. The lower ends of the four support rods on each side rod are hinged together by the rotating shaft. The gas cylinder fixing rings are semi-rings, with their inner diameter matching the diameter of the welded gas cylinder. The outer circumferences of the two gas cylinder fixing rings are respectively connected to the base frame. The upper ends of the two support rods are fixedly connected. The inner circular openings of the two gas cylinder fixing rings are parallel and opposite to each other. The gas cylinder is clamped in the inner circular openings of the two gas cylinder fixing rings. There are connecting plates at both ends of the semi-rings of the two gas cylinder fixing rings. The connecting plates are perpendicularly connected to the outer edge of the front end of the gas cylinder fixing ring along the width of the gas cylinder fixing ring. The plate surfaces of the connecting plates at both ends of the two gas cylinder fixing rings are parallel and opposite to each other. There are corresponding connecting holes on the connecting plates. Two connecting bolts are respectively passed through the connecting holes of the connecting plates at both ends of the two gas cylinder fixing rings. The connecting nuts lock the connecting bolts together.

[0006] The aforementioned foldable transportable welded gas cylinder anti-tipping device has a circular base plate in the middle of the frame where the gas cylinder is placed. The diameter of the circular plate matches the diameter of the gas cylinder. A vertical retaining ring surrounds the circumference of the base plate, and the lower end of the gas cylinder is placed on the base plate.

[0007] The aforementioned foldable transportable welded gas cylinder anti-tipping device has side supports on both sides of the middle of the base frame. The two side supports are rectangular frames, and the two side support frames are on the same horizontal plane as the base frame. One end of each side support is vertically welded to the two side rods of the base frame.

[0008] The aforementioned foldable transportable welded gas cylinder anti-tipping device has vertical fixing plates welded to both ends of the two side rods of the base frame. The fixing plates are square plates with their length direction along the side rods of the base frame. The fixing plates have a shaft hole in their center. The lower ends of the two opposing support rods at both ends of the base frame are welded to both ends of a rotating shaft. The outer ends of each rotating shaft are rotatably connected to the two opposing fixing plates at both ends of the base frame through the shaft hole.

[0009] The aforementioned foldable transportable welded gas cylinder anti-tipping device has four fixing plates welded to the inner sides of both ends of the two side rods of the base frame, the lower ends of the four support rods located on the inner sides of the four fixing plates, and the outer ends of the two rotating shafts rotatably connected to the fixing plates through the shaft holes of the fixing plates.

[0010] The aforementioned foldable transportable welded gas cylinder anti-tipping device has four support rods that are inclined at an angle towards the center of the base frame. The upper ends of the four support rods are bent along the width of the gas cylinder fixing ring. The upper ends of the four support rods are welded to the outer circumference of the two gas cylinder fixing rings respectively.

[0011] The aforementioned foldable transportable welded gas cylinder anti-tipping device uses hollow profiles such as square tubes and round tubes as its base frame and side supports.

[0012] The beneficial effects of this utility model are:

[0013] The base frame and side supports of this utility model can support the welding gas cylinder and prevent it from tipping over. The gas cylinder fixing ring consists of two half rings connected by connecting bolts, which can easily clamp and remove the welding gas cylinder. The lower end of the support rod is hinged to the base frame through a rotating shaft. During transportation, the support rod can be folded down so that the support rod and the gas cylinder fixing ring fit snugly against the base frame, reducing the height of the support rod and reducing the transport space occupied during transportation.

[0014] This utility model has a simple structure, is easy to use and manufacture. It can be folded, occupies little space, and is convenient for transportation. When opened, it can properly support the gas cylinder and avoid safety accidents. Attached Figure Description

[0017] The following are marked in the diagram: base frame 1, side rod 2, side bracket 3, support rod 4, rotating shaft 5, gas cylinder fixing ring 6, connecting plate 7, connecting bolt 8, connecting nut 9, fixing plate 10, bend 11, gas cylinder 12. Detailed Implementation

[0018] This utility model consists of a base frame 1, a side bracket 3, a support rod 4, a rotating shaft 5, a gas cylinder fixing ring 6, a connecting plate 7, a connecting bolt 8, a connecting nut 9, and a fixing plate 10.

[0019] Figure 1 , 2 As shown, the base frame 1 is a rectangular frame placed on the ground. The rectangular frame of the base frame 1 consists of two side rods 2, which are parallel to each other and connected at both ends by crossbars.

[0020] Figure 1 , 2 The display shows that there are side supports 3 on both sides of the middle of the base frame 1. The two side supports 3 are rectangular frames, and the frames of the two side supports 3 are on the same horizontal plane as the frame of the base frame 1. One end of each side support 3 is vertically welded to the two side rods 2 of the base frame 1. The base frame 1 and the side supports 3 form a cross-shaped frame structure, which greatly increases the contact area with the ground and can provide stable support for the gas cylinder 12, preventing the gas cylinder 12 from tipping over.

[0021] Figure 1 , 2 As shown, each end of the two side rods 2 of the base frame 1 has two support rods 4. The lower ends of the two support rods 4 are rotatably connected to the fixing plate 10 through the rotating shaft 5. The fixing plate 10 is connected to the side rods 2 of the base frame 1.

[0022] Figure 1 , 2 As shown, the fixing plate 10 is a square plate. The length direction of the fixing plate 10 is along the side rod 2 of the base frame 1. The fixing plate 10 is placed vertically. The four fixing plates 10 are respectively welded to the inner sides of both ends of the two side rods 2 of the base frame 1. The four fixing plates 10 at both ends of the base frame 1 are parallel to each other.

[0023] Figure 1 , 2The lower ends of the four support rods 4 are located inside the four fixed plates 10. The lower ends of the two opposing support rods 4 at both ends of the base frame 1 are welded to the two ends of a rotating shaft 5. Each of the four fixed plates 10 has a shaft hole at its center, and the outer ends of the two rotating shafts 5 are rotatably connected to the two opposing fixed plates 10 at both ends of the base frame 1 through these shaft holes. The rod body of the support rod 4 is located inside the fixed plate 10. When the support rod 4 is rotated and lowered, the lower end of the support rod 4 will not touch the two side rods 2 of the base frame 1, nor will it touch the fixed plate 10.

[0024] Figure 1 , 2 The diagram shows that the upper ends of the four support rods 4 are respectively connected to two gas cylinder fixing rings 6, and the upper ends of the two support rods 4 at both ends of the base frame 1 are fixedly connected to a gas cylinder fixing ring 6. The gas cylinder fixing ring 6 is a semi-ring, and the inner diameter of the gas cylinder fixing ring 6 matches the diameter of the welded gas cylinder 12. The inner circular openings of the two gas cylinder fixing rings 6 are parallel and opposite to each other, and the two gas cylinder fixing rings 6 are respectively clamped on both sides of the gas cylinder 12.

[0025] Figure 1 , 2 The diagram shows that each end of one of the two cylinder fixing rings 6 has a connecting plate 7. The connecting plate 7 is perpendicularly connected to the outer edge of the front end of the cylinder fixing ring 6 along its width, and the surfaces of the connecting plates 7 at both ends of the two cylinder fixing rings 6 are parallel and opposite to each other. The connecting plate 7 can be welded to both ends of the cylinder fixing ring 6 with a square steel plate, or it can be integrally bent into shape with the cylinder fixing ring 6. The connecting plate 7 has corresponding connecting holes, and two connecting bolts 8 are respectively inserted into the connecting holes of the connecting plates 7 at both ends of the two cylinder fixing rings 6. The connecting nuts 9 lock the connecting bolts 8 in place, so that the two cylinder fixing rings 6 are clamped to the outer circumference of the cylinder 12.

[0026] Figure 1 , 2 The diagram shows that the outer circumferences of the two gas cylinder fixing rings 6 are connected to the upper ends of the four support rods 4. The four support rods 4 are inclined at an angle towards the center of the base frame 1, and each of the four support rods 4 has a bend 11 at its upper end, which runs along the width of the gas cylinder fixing rings 6. The bends 11 are welded to the outer circumferences of the two gas cylinder fixing rings 6. The bends 11 fit snugly against the outside of the gas cylinder fixing rings 6, increasing the welding contact area between the support rods 4 and the gas cylinder fixing rings 6, and improving the installation strength of the support rods 4 when supporting the gas cylinder 12.

[0027] Figure 1 , 2 The display shows that the base frame 1 and the side support 3 are hollow profiles such as square tubes and round tubes, which can be square steel tubes, round steel tubes, or aluminum alloy tubes. The base frame 1 and the side support 3 are made of hollow profiles by bending, which can reduce the overall weight of the anti-tipping device and facilitate handling and transportation.

[0028] The usage process of this utility model is as follows:

[0029] When in use, place the lower end of the gas cylinder 12 on the middle base plate of the base frame 1, rotate the support rod 4 so that the support rods 4 on both sides of the gas cylinder 12 drive the two gas cylinder fixing rings 6 to fit against both sides of the gas cylinder 12; insert the two connecting bolts 8 into the connecting holes of the connecting plates 7 at both ends of the two gas cylinder fixing rings 6 respectively, and tighten the connecting bolts 8 with the connecting nuts 9 so that the two gas cylinder fixing rings 6 are clamped on the outer periphery of the gas cylinder 12, thus completing the fixing of the gas cylinder.

[0030] After using the gas cylinder 12, loosen the connecting nut 9, remove the connecting bolt 8, separate the gas cylinder 12 from the gas cylinder fixing ring 6, remove the gas cylinder 12 from the middle base plate of the base frame 1, and then rotate the support rod 4 so that the support rod 4 is pressed downward against the base frame 1. This reduces the height of the device, reduces the transport space occupied during transportation, and facilitates the transport of the foldable anti-tipping device.
